I know nothing about the smartstrike, but I do use the contour elite. The elite has worked out very well using it to do a map recon and check the area's point's , flat's, inlets and so on. It has been a well used tool. I use the navionics chip a lot because of the stumps, and hazard area's because lakemaster really doe's not explain the hazard area's as well as the navionics does. Hope this helps you or answers your questions. Tight lines.
